Copying file "Calculates" Forever - Windows 10 - Surface 3 and Surface 4

I have three Surface Tablets with Windows 10 that all have the same problem.

When I try to copy a file over wifi, the copy file dialog window sits at 0% and "Calculating" forever.

The workaround is to refresh the destination folder in Windows Explorer (right-click in folder>refresh).

I would like to fix whatever is causing this issue.

What I know:

All the surface tablets can get out to the internet with good speeds.

This issue does not occur on my Surface Pro 2 with Windows 8.

This issue did not occur on my Surface Pro 3 with Windows 8

This issue does occur on my Surface Pro 3 after upgrading to Windows 10.

This issue does occur on my Surface Pro 4 with Windows 10.

This is not a problem on various other Windows 10 laptops connected to the same Wifi.

There is ample hard drive space for the copy operation. (5TBs available for a 47MB file)

The file transfer happens successfully, but the window never shows it and will sit there forever.

Trying to close or cancel the window freezes the Surface for several minutes and never works.

Refreshing the destination folder (a network drive) on the Surface tablet is the only way to get it to stop "Calculating".

Please assist. This is incredibly frustrating. It took me weeks to figure out the workaround and I can't find any help about this issue.

    Are you copying to a NAS drive or ?? Which brand/model?

    Hi Barb,

    Yes, a NAS drive. Dell PowerEdge R730. I'll look into those posts as soon as I get a chance. Thank you.

    So I followed up on both those links. Both of them talk about the internet connection being very slow. That doesn't seem to be my problem. I'm not actually seeing any transfer speeds at all. Also, I know that the file sometimes transfers successfully and much faster than 3 KB/s, but the device remains unresponsive anyway.

    I should add that I have worked around this problem by restarting the tablet and making the file transfer the very first thing I did. This workaround no longer works, and it was incredibly impractical from the start. The other workaround I had where I refreshed the destination folder also no longer works.

    Unfortuantely, I am not experiencing my issue today. It usually 90% of the time. Today is the rare 10%. Regardless, I looked through the posts and applied some of the changes such as disabling checksum offload and Large Sum Offload. No change over wifi, which is expected because these were only options for the physical connection driver (not the wifi driver).

    Interestingly, I am experiencing a new issue. I see interesting valleys in the copying speed. Each valley is a several second slowdown from about 4-6 MB/s to 0 KB/s and it sits at 0 for a while.

    The following image shows it happening with a single file (size 35 MB). Repeat tests had the valley showing up in all different locations throughout the life of the copy operation (not just at the very end).

    This next image shows it happening with 44 jpeg files (size 160 MB total).

    I would like to avoid fixes like "wipe the machine and install windows again." That's obviously a last resort, and from what I've seen online, some problems still persist. It's also a problem with several machines.

    Edit: Grammar mistakes

    what do you see if you copy the same files from one Surface to another as opposed to the NAS?

    This morning I attempted to copy from Surface to Surface. The only way I know how to do this is with the Map Network Drive tool, so I hope that's what you meant.

    The good news is, I was able to reproduce my original error. Copying from Surface to Surface resulted in a Surface frozen on the Calculating screen, but the file does copy.

    5 minutes later I tried copying to the NAS again and got the same results I was getting yesterday (the "valleys"). Then I retested the Surface to Surface over the Map Network Drive and got the valleys issue.

    Edit: Added more test results. Grammar.
